The death of a 10 year old boy who was buried by a collapsing sand dune on the far South Coast has raised concerns about large dunes at Shoalhaven Heads.

The boy was playing on a beach at Eden when the dune fell and crushed him on Monday afternoon.

Dunes at Shoalhaven Heads near Nowra, are currently four to six metres tall following recent high tides.

Shoalhaven Heads Surf Life Saving Club President Karl Poulton said he's concerned a someone else might be hurt if the community isn't better educated.

"Practically, I don't think there's a lot that council or anyone can do."

"In light of what happened down the coast and some of those significant dunes that we're seeing, I guess we're just looking for some education so people are little bit conscious when they come down," Mr Poulton said.

"We are in discussions with council and what we would like to see is some increased signage."

He said the tragedy means life guards and parents will have to be vigilant in looking out for the safety of children beyond the water.

"I guess from a surf club point of view, we have to be more diligent when we're on patrol."

"We have to start advising people that if they're near the dunes they could be unstable," Mr Poulton said.

"Whilst it won't be a huge impost early in the season, come Christmas, New Year and the January School Holiday, when Shoalhaven Heads' transient population increases significantly, it is going to put an extra burden on our resources."

The surf club is drafting a letter to Shoalhaven Council urging the organisation to consider erecting more signs around Shoalhaven Heads beach.
